Many doctors will use the term dystonia but the spasms we often have w/TOS is not true dystonia. Dystonia/Torticollis is a movement disorder and generally results in a tilt to one side and possibly uncontrollable jerks. This is treated often with ultrasound guided Botox to specific muscles. I don't know if the scalenes are often (or ever) implicated with dystonia, so scalenectomy is not a treatment for it.
